Filed: 1956-05-12
Abstract: 811,356. Sealed bearings. BURTONWOOD ENGINEERING CO. Ltd. Feb. 27, 1957 [May 12, 1956; July 25, 1956], Nos. 14830/56 and 23005/56. Class 12 (1). [Also in Group XXVI] A seal for a ball or roller bearing comprises a ring 11, Figs. 1 and 2, of rubber or like material, which has one edge entering a groove 6 formed in one race 7 and the other edge formed as a lip 5 bearing on the other race 8, and a reinforcing ring 12 which is bonded to or embedded in the ring 11 and has one of its edges disposed adjacent that edge of the ring 11 entering the groove 6, there being in the unreinforced part of the ring 11 at least one annular zone 14, Fig. 1 or 16, Fig. 2, of less thickness than the remainder of that part to provide a resilient hinge area about which the lip 5 may be displaced axially. The reinforcing ring 12 may be of metal or moulded plastic material. Stiffness is provided in the embodiments shown in Figs. 1 and 3 by annular corrugations 13 and 17 respectively and in each the reinforcing member contacts the locating groove 6 in the outer race 7. Alternatively, corrugations may be radial or both radial and annular. In the construction shown in Fig. 2, the reinforcing member 12 is stiffened by beading or folding its outer edge, the reduced thickness portion 16 allowing for the flexing of the lip portion 5 against the arcuate contacting part of the inner race. In Figs. 1 and 3, flexibility is provided by forming necks 14 and 19 respectively nearer the inner margins of the resilient annular elements. The plane containing the section of minimum thickness is set at an angle in Fig. 3 and the inner edge of the reinforcement 17 lies at the outer boundary of the portion 18 of reduced thickness. Fig. 4 shows a further modification in which the neck portion 23 is adjacent the inner boundary of the reinforcing member 21 which is rolled or swaged to provide a partly embedded arcuate section 22 to abut against the outer race 7. The median plane of the area of reduced thickness, or when there is more than one such area as in Fig. 4, of that area nearest the sealing lip, may be parallel with or contained by the median plane of the seal as a whole or at an angle thereto as in Fig. 3. The sealing lip may be moulded so that when unstressed it extends out of the plane of the annular member towards the bearing, or the reinforcement may be formed with a notched edge to provide teeth having a slight axial set towards the face to be sealed. The reinforcing ring may also be apertured to provide a key for the rubber covering. Alternative arrangements are described in which the sealing lips contact the outer races and the rigid parts are secured in grooves in the inner races. The seals may be of different colours at opposite sides of the bearing to indicate the respective ends of, for example, a semi-thrust bearing. Self-sealing lubricating apertures may be provided in the seals. The second Provisional Specification states that the reinforcing element need not be embedded in or bonded to the rubber-like element.

Title: Process for the manufacture of coloured photographic materials
IPC: G03C1/83
Filed: 1937-05-31
Abstract: Coloured layers for photographic use are prepared by introducing into the solution for producing the layers or into the formed layers, soluble dyestuff derivatives especially bisulphite and aldehyde bisulphite compounds of azodyes, which are capable of being split up by hydrolysis especially by the components of photographic treatment baths.  The layers may be used as anti-halation or filter layers or the dyestuff derivatives may be incorporated in sensitive layers, for example for use in the formation of dyestuff images by destruction of the dye in the presence of the silver image.  Suitable dyestuff derivatives are formed by coupling sodium methylaniline-o -sulphonate with a diazo compound, e.g. diazotized p-nitraniline.  In examples: (1) filter layers are formed by dyeing gelatin layers with the bisulphite compound of Para Red and bathing in sodium carbonate solution; (2) filter layers may be formed by dyeing gelatin with the red dye formed by coupling diazotized p - nitraniline with o-anisidine, diazotizing and coupling the product with the sodium salt of b -naphthylamine-o -sulphonic acid; (3) a light-sensitive layer is treated as in (1) above; (4) a silver halide emulsion layer sensitized with pinacyanol is treated as in (2) above; (5) a light-sensitive emulsion is dyed with the bisulphite compound of the dye derived from diazotized 2 : 5-dichloraniline and b -naphthol and the compound split up in situ; subsequently a silver image is formed therein and the dyestuff destroyed at the image portions by a bath comprising thiocarbamide, hydroquinone, methyl alcohol, and hydrochloric acid.  The splitting up of the dyestuff derivative may be effected after the application of the dye destruction bath; (6) by using a mixture of a blue-green dye, e.g. Diamine Pure Blue, and a yellow bisulphite compound which yields a red dye, e.g. Para Red, a black layer may be produced after the splitting up of the bisulphite compound.  Other dyestuff derivatives which may be used are the salts of sulphaminic acid for example, the salt of the product of coupling diazotized p-nitraniline or nitrotoluidine with b -naphthylamine or with the sodium salt of b -naphthylamine-o -sulphonic acid.  Other dyes are those formed by coupling the sodium salt of a -naphthyl sulphaminic acid with tetrazotized dianisidine or diazotized p-nitraniline, by coupling p-nitraniline with b -methoxy-a -naphthylsulphaminic acid, by coupling diazotized aniline with sodium phenylsulphaminic acid, and by coupling 2 : 3-oxynaphthic acid with diazotized a -naphthylamine or dianinostilbene disulphonic acid.  The combination of diazotized nitraniline and o-anisidine with a -naphthylamine-methyl-o -sulphonic acid and of tetrazotized dianisidine with b -naphthylamine-methyl-o -sulphonic acid may also be used.  Multilayer material of which one or more layers include the derivatives may be used for colour photography. Specification 397,159, [Group XX], is referred to.
